Open TMS

Overview

Open TMS is an open-source system for coordinating freight and warehouse operations from order intake through delivery. It best suits shippers, 3PLs, carriers and warehouse teams that need these workflows under one roof. Its free, MIT-licensed plan avoids per-user and transaction fees, but organizations should be ready to handle deployment and setup.

Key features

Orders, carrier workflows and tracking

Orders can enter by CSV, EDI 850, REST API or manual entry, then move through lane matching, multi-stop routing and shipment tracking. Broadcast and waterfall tenders, a carrier bidding portal and EDI 204/990 tendering support different approaches to sourcing capacity. This breadth is useful for operations with varied carrier processes; a business that only needs a tracking view may find the system broader than necessary.

The EDI hub supports X12 transactions 850, 855, 856, 204, 990, 997, 214, 210, 810 and 820, delivered over SFTP or HTTP. Tracking integrations for FedEx, UPS and DHL use OAuth 2.0 or API keys. GPS and sensor telemetry feed traffic-aware ETA monitoring, using TomTom, HERE or self-hosted Valhalla routing. Together, these options can connect order, carrier and location workflows, while teams should expect to configure the integrations that fit their operation.

Warehouse, mobile and compliance

The warehouse module handles receiving, putaway, picking, packing, load planning, inventory and returns alongside shipments and orders. A scan-first progressive web app supports warehouse tasks and barcode scanning with Zebra and Honeywell RF guns through a barcode wedge hook. That makes it relevant to teams that want warehouse execution in the same system, rather than a separate inventory-only tool.

For temperature-sensitive operations, the maker describes CFR 21 Part 11 compliant logging with SHA-256 integrity hashes, excursion detection and automatic quarantine workflows. Developer webhooks use HMAC-SHA256 signatures, a five-minute tolerance window and exponential-backoff retries of up to five attempts. These are practical controls for compliance-sensitive workflows and integrations; organizations should assess whether the workflows meet their own requirements.

Pricing

The Open TMS plan costs nothing, billed Free forever. It is MIT licensed, has no per-user fees or transaction costs, and imposes no feature gates. Inventory tracking, shipment tracking, order management and document management are included. This is an unusually open cost structure for teams expecting multiple users or transaction volume, though it does not remove the work of running the system.

Open TMS can be deployed with Docker Compose, on AWS, GCP, Azure or DigitalOcean, or on self-hosted infrastructure. Professional installation, setup and ongoing support are available as consultancy services, so teams that need implementation help should account for that service relationship.

Platforms

Open TMS is available as a web application and supports API and self-hosted deployment. Docker Compose and deployments across major cloud providers give organizations choices about where to operate it, but those choices also place infrastructure decisions with the customer.

Who it's for

The product is aimed at shippers, 3PLs, carriers, warehouse teams, quality managers and compliance officers. Its strongest fit is an organization that needs transportation, warehouse and compliance workflows together and has the resources to manage an open-source deployment. Teams looking for a narrowly focused tracking product or a turnkey hosted service should consider whether this operational scope and deployment responsibility suit them.

Pros and cons

• Pro: The free-forever MIT plan has no per-user fees, transaction costs or feature gates, making it suitable for operations that need broad access without usage-based charges.
• Pro: Transportation, carrier, warehouse and inventory workflows share one system, reducing the need to split those tasks across separate tools.
• Pro: Multiple deployment options, EDI delivery methods and carrier tracking integrations give technically equipped teams flexibility in how they connect and operate the system.
• Con: Deployment and setup require infrastructure ownership or consultancy, which may not suit teams seeking a managed, ready-to-use service.
• Con: The wide operational scope may be unnecessary for organizations that only need basic shipment visibility.

Verdict
